ELECTRIC RAILWAY.

SPECIFICATION forming part of Letters Patent No. 432,623, dated July 22, 1890.

Original application iiled .I une 9, 1886, Serial No.

To all whom it may concern:

Be it known that I, RUDOLPH M. HUNTER, of Philadelphia, in the county Vof Philadelphia and State of Pennsylvania, have invented an Improvement in Electric Railways, of which the following is a specification.

My invention has reference to electric railways; and it consists of certain improvements, all of which are set forth in the following specification and shown in the accompanying drawing, forming a part thereof.

Y This application (Case 132) is a division of my application No. 204,583, filed June 9,1886.

My invention comprehends means for propelling and lighting a vehicle from the same source of power, whether it be from line-conductors leading from a stationary source of power or by batteries carried on the car. I The electric lamps are connected in multiple with respect to the motor and are provided with independent regulating mechanism from that employed for eontrollin g the speed of th e motor.

In the drawing is shown a sectional elevation of an electrically-propelled vehicle embodying my invention.

A is the source of power and B B are the positive and negative conductors extending along the railway, and may be arranged in a conduit or suspendedl above the car or on the surface of the ground, as desired.

C is the rails, and, if desired, said rails may be used as the return-cond uctor. v

D is the car-body, and is supported upon wheels in the usual manner.

Carried by the axles F is a frame G, upon which the electric motor II is secured, and which motor gears with the axles by gearing for in any suitable manner.

J is the 1notor-circuit, and connects with the conductors B by collectors L.

M is a regulator for controlling the current passing to the motor.

In place of the line-conductors B and stationary generator A, a battery A ot' the primary or secondary type may be the source of power and carried on the car.

P represents electrical lamps arranged in' multiple in circuits 0, which connect with the motor-circuit J upon opposite sides of the motor H, and so as to be arranged in multiple with 204,583. Divided and this application filed March 27, 1890. Serial No.

the motor. Each of the lamps is provided with a switch p for cutting out either lamp independently of the others.

O is a resistance-changer in thelamp-eircuit O, and is operated bya helix and core O2, the helix being arranged in a shunt O3in` parallel with the lamps.

m is an indicator to indicate the current owing in the lan'ip-circuit.

E is a switch for cutting the lamp-circuit in and out of operation.

P represents a series of lamps which may be employed in place of the multiple arrangement above referred tof The automatic resistancechanger is designed to work automatically to increase the resistance in the lamp-circuit upon the resistance in the motor-circuit being increased, so

far as the current passing through the motor is concerned, so that when but little current is passing through the motor a greater resistance is thrown into the lamp-circuit, and vice versa, to maintain the lamps burning at a constant candle-power.

I do not limit myself to any particular arrangement of resistance-changer, as the saine maybe automatic or otherwise. I do not con line myself to any particular arrangement of lamps nor to any special type of regulator for the motor, as all of these may be modified in various ways without departing from my invention.

The construction and arrangement of the motor on the ear are not claimed in this application, but form subject-mattei' of my appli cation of which this is a division.

Having now described my invention, what I claim as new, and desire to secure by Letters Patent, is-

l. The combination of a source of electric supply, a traveling' vehicle, an electric motor carried thereby, a shuntfcircuit upon said vehicle and receiving electricity from the same source as the motor, electric lamps in said shunt-circuit, and an indicator to indicate the current flowing through said shunt-circuit.

2. The combination of a source of electric supply, a traveling vehicle, an electric motor carried thereby and arranged to rotate the vehicle-axle, a shunt-circuit upon said Vehicle IOO and receiving electricity from the same source as the motor, electric lamps in said shunt-circuit, a resistance-changer to control the current flowing through the lamps, and an indicator to indicate the current flowing through said slumt-circuit.

3. The combination of a source of electric supply, a traveling Vehicle, an electric motor carried thereby and arranged to rotate the vchicle-axle, a shunt-circuit upon said vehicle and receiving electricity from the same source as the motor, electric lamps in said shunt-circuit, an automatic resistance-changer to control the current flowing through the lamps, and an indicator to indicate the current flowing through said shunt-circuit.

4. The combination of a source of electric supply, a traveling vehicle, an electric motor carried thereby and arranged to rotate the vehicle-axle, a shunt-circuit upon said vehicle and receiving electricity from the same source as the motor, electric lamps in said shunt-circuit, and a resistance-changer to control the current flowing through the lamps.

5. The combination of a source of electric supply, a traveling vehicle, an electric motor carried thereby and arranged to rotate the vehicle-axle, a shunt-circuit upon said vehicle and receiving electricityfrom the same source as the motor, electric lamps in said shunt-circuit, and an automatic resistance-changer to control the current tlowin g through the lamps.

6. The combination of a source of electric supply, a traveling vehicle, an electric motor carried thereby and arranged to rotate the vehicle-axle, a shunt-circuit upon said vehicle and receiving electricity f rom the same source as the motor, electric lamps in said shunt-cir cuit, a resista-nce-changer to control the current flowing' through the lamps, and separate switches to cut out each lamp.

7. The combination of a source of electric supply, a traveling vehicle, an electric motor carried thereby, ashunt-circuit upon said vehicle and receiving electricity from the same source as the motor, electric lamps in said shunt-circuit,an automatic resistan ee-chan ger to control the current flowing through the lamps, separate switches to cut out each lamp, and a single switch to cut out all of the lamps.

S. The combination of a source of. electric supply, a traveling vehicle, an electric motor carried thereby, a shunt-circuit upon said ve hicle and receiving electricity from the same source as the motor, electric lamps in said slnintcircuit, a variable resistance in said lamp shunt-circuit, a second circuit forming a shunt around the lamps, and an electric device, substantially as set out, in said second circuit, to actuate or regulate the resistance in the first or lamp shunt-circuit.

In testimony ot which invention I have hereunto set my hand.
